What's happening here?

This example introduces the fundamental concept of UIFullscreenLayer - the base container for all UI elements in Laymur. A single image is displayed without any constraints, showing the basic setup for rendering UI elements in a Three.js scene.

// Create the UI layer
const layer = new UIFullscreenLayer(
  1920, // Fixed width
  1920  // Fixed height
);

// Add an image to the layer
new UIImage(
  layer,
  baseScene.loadedTextures["T_Download"]
);

// Render the layer
layer.render(baseScene.renderer, deltaTime);
